Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147491102, here are decompositions:

11 + 2147491091 = 2147491102
41 + 2147491061 = 2147491102
59 + 2147491043 = 2147491102
83 + 2147491019 = 2147491102
101 + 2147491001 = 2147491102
149 + 2147490953 = 2147491102
179 + 2147490923 = 2147491102
269 + 2147490833 = 2147491102

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.0.29.30.
